Why Professional Teeth Whitening Transforms Your Smile
At Prostho Cosmetic Dentistry, our professional whitening treatments go far beyond what over-the-counter products can achieve. Using professional-grade whitening agents and customized application techniques, we effectively remove deep stains and discoloration from within the tooth structure, not just on the surface. The result is a dramatically brighter smile that still looks naturally beautiful, not artificially white.

We offer both in-office treatments for immediate results (perfect before special events) and custom take-home systems for gradual whitening at your convenience. Both options are supervised by our dental professionals, ensuring optimal results while protecting your teeth and gums from the sensitivity and damage that can occur with improper whitening methods.
Many patients are amazed by how much younger and more vibrant they look after just one whitening session. Often the most dramatic smile enhancement you can achieve without altering your natural tooth structure.

At Prostho Cosmetic Dentistry, our whitening procedures stand apart through a personalized approach that recognizes no two smiles are identical. Before any whitening begins, we conduct a comprehensive shade assessment and stain analysis to determine the specific causes of your discoloration and the optimal whitening protocol for your unique situation whether it's extrinsic staining from foods and beverages or intrinsic discoloration from medications or aging.
This detailed evaluation informs our customized treatment recommendations, which may include specialized techniques for sensitive teeth or resistant stains that don't respond to standard whitening approaches. For in-office treatments, we utilize advanced light-activated whitening systems with built-in desensitizers and pH balancers that maximize effectiveness while minimizing sensitivity.
Our take-home options feature custom-fabricated trays that fit precisely against your teeth, ensuring even whitening while protecting gum tissue from irritation. This is vastly superior to one-size-fits-all drugstore kits.
We further enhance results through pre-whitening protocols that optimize enamel receptivity and post-treatment maintenance systems that extend the longevity of your brighter smile.

Frequently Asked Questions About Teeth Whitening
Yes, but we’ll modify your treatment plan. Lower concentration whitening gel, reduced treatment duration, and specialized desensitizing products help protect sensitive teeth while still achieving excellent results.
This is an important distinction. Standard teeth whitening (external bleaching) works on natural, vital teeth by penetrating the enamel from the outside. However, when a tooth has had root canal treatment, it may darken from the inside due to internal tissue changes or treatment materials. For these teeth, we perform “internal bleaching” (walking bleach technique), where we place whitening agent inside the tooth chamber and seal it temporarily. This treats discoloration from within the tooth structure. A completely different approach that specifically addresses the unique discoloration that can affect root canal-treated teeth.
Professional whitening is generally recommended only after all permanent teeth have fully erupted. Typically around age 16 or older. Treatment for younger patients requires careful professional supervision.
We recommend scheduling 2–4 weeks before your event. This timeline allows for any temporary sensitivity to resolve and provides flexibility for touch-up treatments if desired.
Professional teeth whitening at Prostho Cosmetic Dentistry is highly effective for most types of discoloration but does have limitations for certain conditions.
Extrinsic stains are those caused by external factors like coffee, tea, red wine, berries, and tobacco. It respond excellently to whitening, often improving by 5-8 shades. Age-related yellowing, which results from natural enamel thinning that reveals the yellowish dentin beneath, also responds very well to professional whitening.
However, some types of discoloration have limited or no response: intrinsic stains from certain antibiotics (particularly tetracycline) may show only modest improvement even with extended treatment; discoloration from developmental conditions affecting enamel formation often requires alternative treatments; white spots from fluorosis or demineralization may actually become more noticeable after surrounding enamel brightens; and teeth with restorations (fillings, crowns, veneers) won't change color with whitening. An important consideration for visible restorations that might no longer match after treatment.
During your whitening consultation, we perform a detailed evaluation to identify your specific type of discoloration and provide realistic expectations about treatment outcomes.
For cases where whitening alone isn't sufficient, we offer alternative cosmetic options like bonding, veneers, or combination approaches. Uncertain about whether whitening will address your specific concerns?
